Cut each chicken wing into three portions: drumette, middle portion and tip. Discard the tip of the wings and place the other portions in a large bowl.
Make the Moroccan rub by mixing together the ground cumin, ground coriander, paprika, ground cardamom, ground cinnamon, ground cloves, ground nutmeg, cayenne pepper, salt and sugar. Toss the wings in the seasoning so they are evenly coated.
Set up Smoker for 121°C (250°F) using wood bisquettes of choice.
Lay wings on smoker racks and smoke for 2 – 2 ½ hours or until cooked through.
Blend together all ingredients for the Harissa paste in a blender or food processor until smooth. Add more oil if necessary to reach the right consistency.
Rub lamb shanks generously in Harissa paste and let marinate overnight (or a minimum of two hours before smoking).
